TBD: sostituire le opzioni di boot con quelle disponibili nel SOC e nella Carrier

Boot Configurations[edit | edit source]

ETRA Evaluation Board is built upon STM32MP1 processor.

The following sections detail boot configuration options, which differ depending on the SoM.

Available options[edit | edit source]

Boot modes can be selected by S1 DIP-switch which act directly on BOOT_MODE[0..2] configuration pins.

S1 switches are mapped to BOOT_MODE[0:2] pins allowing different boot modes.

The different boot modes can be found in the following table:

DA RIVEDERE

DIP settings[edit | edit source]

BOOT_MODE[0:2] Boot sequence Notes
0111 MMC0/SPI0/UART0 Default boot from NOR SPI
0011 NAND/NANDI2C/MMC0 boot from NAND
1001 SPI0/MMC0/EMAC1 boot from EMAC if DIVA has no NOR and no NAND on board
